Richard Purdie 0d298198e5 qemu: Upgrade 5.1.0->5.2.0
This involves some pretty major changes for qemu. In particular, they
switched to meson+ninja so we have to adapt to that.

Patch changes:
* CVE patches - dropped as backports
* cflags fix - upstream code changed significantly, need new patch if still issues
* mips TLB entries - dropped as merged upstream
* usb fix - dropped as merged upstream
* find_datadir - dropped as code no longer present that I could find

A patch was added to allow us to force the configure script into "cross" mode
without setting cross_prefix which has other effects we don't need/want.

Dependencies on meson/ninja were added.

Specifying the python interpreter causes the internal meson copy to be
built/used which is undesireable for us so don't do that. The correct
python is in PATH anyway.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
